Quite a few if you count GFCIs going bad, they need to be replaced periodically. (If you test them you’ll also find that they really do have a failure mode where they keep delivering power but will no longer trip, which is a lot less noticeable than when they trip and won’t reset.)

But to your actual point: I have a feeling they’re just badly engineered. Tesla ones are so much more reliable than third parties. I’m not sure if that’s because they break less or are fixed faster, and I suspect it’s some of both, but the difference is very large.
